Setup procedures—Part 1

HF SSB transceiver reference manual 5-9

The higher the Golay value calculated for a received ALE

word, the greater the error.

If a received ALE word contains more errors than the Golay

Threshold, the ALE controller rejects the word. The lower

you set the Golay Threshold, the greater the likelihood of

rejecting words with errors.

Error Threshold (ALE option 7)

This ALE option sets the maximum number of sequentially

received bad ALE words that are allowed before the ALE

controller decides that the quality of the current channel is

too poor to establish an ALE link. A bad word is a word that

has exceeded either the BER or Golay Threshold.

You can set a value in the range 0–4.

If the test fails during the process of establishing the ALE

link, the call aborts and the transceiver returns to Scan

mode.

ALE Silent Mode (ALE option 11)

This ALE option switches on or off ALE Silent mode.

When ALE Silent mode is switched off, the station runs as a

normal ALE station.

When ALE Silent mode is switched on, the station will not:

• recognise any incoming ALE calls

• send or receive sounding signals even if Sounding

On/Off (ALE option 0) is switched on.

You can still send ALE calls in ALE Silent mode.
